There has been some talk of this on the wiki: http://wiki.openstreetmap.org/wiki/OSM_GPS I do some electronics and PIC programming as part of my work and for personal projects, so I've decided to try to make a small geotagging camera. I've already purchased a camera and GPS, and am now trying to shoehorn those, plus PIC, power supply, two AAs, SD card and connector, and a couple of switches into the smallest (currently 65x60x40mm) IP67 sealed (clear lid for camera) box I can. If I can figure out how to fit everything, I'll design a PCB or two and start on the firmware. Some pricing context: GPS: Globalsat EM-408: USD$48 Colour VGA camera, Electronics123: USD$48 Add the PCBs and it's probably another USD$50. Add the box, PIC, other components and freight and you'll probably get another USD$50. When it comes to electronics, you cannot compete with the economies of scale of the mass-market. Having said all that, *would* anyone be interested in a ~USD$200 640x480 geotagging camera and GPS logger? I'm not doing this particularly with the idea of going into production. I'm doing it mainly because I've always wanted to get some experience interfacing to SD cards. I have to admit it's also a pretty cool idea. ;-) -- Andrew Gregory <mailto:and...@scss.com.au> _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
